When this is performed, a representative signal corresponding to the detected abnormality is output from representative output terminals 32-1 to 32-1 provided in the terminal control unit 20.
32-4. For example, if an on/off type fire detector connected to the signal line 22 generates a fire detection output, then the representative output terminal 32 of the terminal control unit 20 -
A representative fire signal is output to 1, and the backup repeater 34

を示す火災警報とその表示を行なうようになる。The receiver 10 learns that it is the representative fire signal from the relay board 12-1 by decoding the disaster prevention information from the relay board 12-2, and the receiver 10 has already detected the relay that has caused the failure. Since normal disaster prevention control between the relay panel 12-1 and the relay panel 12-1 is no longer possible, a fire alarm indicating the area where the fire occurred is based on the representative fire signal received and deciphered from the faulty relay panel 12-1. and its display will be performed.

However, if the relay board 12-1 is operating effectively due to reception decoding processing on the receiver 10 side, the backup disaster prevention information from the relay board 12-2 is ignored. You should do it. Of course, relay board 12-
It is also possible to perform processing in which no transmission is performed to the receiving gJ110 from 2 onwards.

ことができる。[Effects of the Invention] As explained above, according to the present invention, a failure that makes transmission to a receiver impossible can occur during tl! Even if a fault occurs in a faulty relay board, the detection signal from the disaster prevention sensor connected to the faulty relay board by the signal line is sent as a representative signal to the backup repeater connected to the signal line to another normally functioning relay board. is,
The representative disaster prevention information can be transmitted from the backup repeater to the receiver via another repeater, and backup transmission can be performed by effectively utilizing the functions of the normal repeater and transmission path.
また、バックアップ線は隣接した監視区域をもつ中継盤

継盤のバックアップ処理を確実に行なうことができる。In addition, since the backup line can be wired between relay boards with adjacent monitoring areas, the wiring length can be shortened even more if the backup line is wired between the receiver and the receiver.
There is no need to increase the number of signal lines in the original transmission line, and there is no need to provide a receiving circuit dedicated to the backup line on the receiving side, so a simple backup configuration can reliably perform backup processing for a faulty relay board. Can be done.
